Summary: This article explored the adsorption-desorption processes of typical heavy metal pollutants in sediments under different conditions and designed different binary competitive adsorption systems to study the competitive adsorption properties of heavy metal contaminants. The sediment adsorption rates for heavy metals were Cu>Pb>Cd>Zn, and the desorption rates were Cd>Cu>Zn>Pb. The removal of organic matter decreased the ability of sediment to sequester heavy metals, and interfering ions had the greatest effect on Cd and the least effect on Pb. The adsorption and desorption of heavy metals in sediments increased with temperature, and the presence of organic matter increased the sequestration ability of sediment for Cd, Pb, Cu, and Zn. Heavy metals also exhibited significant selective adsorption properties.

Summary: The development of low-cost, high-efficiency, and environmentally friendly adsorbents for the removal of antibiotics and heavy metal ions in water is urgently needed. Phosphorylated alkali lignin (PAL) microparticles were successfully fabricated via a simple one-pot method, showing great potential in adsorption of pollutants such as levofloxacin hydrochloride (LH) and lead ions (Pb(II)). The results demonstrated that PAL had a strong ability to remove complex pollutants, with high adsorption capacity and removal percentage for various contaminants in water.

Summary: Bone-derived biochar loaded with Fe3O4 (MBBCBM) was synthesized by ball-milling process and exhibited excellent adsorption capacities for Pb(II) (339.39 mg/g) and TC (237.51 mg/g) in water. The adsorption process achieved equilibrium within 20/100 min and was well described by Avrami fractional-order model. The MBBCBM demonstrated high stability over a wide pH range, tolerance to co-existing ions, and retained its adsorption performance after three cycles.

Summary: The research focused on improving the adsorption efficiency of geopolymer as an adsorbent for heavy metal ions and dyes removal. The adjustment of pH enhanced the rapid removal of methylene blue and nickel ions by exposing more negative charge adsorption sites. Additionally, the study found that the desorption of nickel ions was facilitated by a decrease in pH of the wash solution.

Summary: This study comprehensively explored the effects of UV aging and environmental factors on the adsorption of heavy metals by microplastics (PP, PE, and PS). The results showed that aging enhanced the hydrophilicity and oxidation of microplastics, leading to increased adsorption capacity for contaminants compared to pristine microplastics. The adsorption amounts of Pb(II) and Cu(II) by PP, PE, and PS increased by 1.45, 1.46, 1.25 and 1.63, 1.39, 1.22 times, respectively. The adsorption process was governed by chemisorption and nonhomogeneous multilayer adsorption. In a binary composite system, the adsorption capacity of metal ions on microplastics was lower than that in a single system due to a specific inhibitory effect of coexisting ions. External factors such as pH, salinity, and fulvic acid content significantly influenced the adsorption behavior, which was mainly attributed to electrostatic interaction, surface complexation, and van der Waals forces.

Summary: This review explores the co-exposure of microplastics (MPs) and heavy metals in the marine environment and emphasizes the need for effective remediation strategies. The study reveals various mechanisms by which heavy metals can be adsorbed onto MPs, with biofilm formation on MPs impacting metal adsorption behaviors. Thermodynamic models explain the adsorption mechanisms, while factors such as MPs' morphological characteristics, adsorption capacity, and environmental conditions influence the process. The desorption of heavy metals from MPs poses risks to marine organisms, underlining the importance of source reduction and remedial measures.

Summary: This study compared the adsorption behavior of lead (Pb(II)) onto environmentally-relevant tire wear particles (TWP), ultraviolet-aged polylactic acid microplastics (UV-PLA), and ultraviolet-aged polystyrene microplastics (UV-PS). The results showed that aging processes significantly improved the adsorption capacity of Pb(II), with TWP having the highest adsorption amount. The mechanisms of adsorption differed for each type of microplastic, with electrostatic interaction and complexation playing important roles. Furthermore, the presence of humic acid affected the adsorption capacity, and the desorption ability of Pb(II) varied among the different microplastics.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
